Developing guitar speed has a reputation for being either a dark art or a brute-force grind. Neither is true. There is solid science behind it, and once you understand that science, the path forward becomes much clearer — and much kinder to your body.
What you’ll get out of this lesson
This is a recording of the Speed Science for Guitarists lecture from the first GuitarVivo Modern Guitar Summit in December 2021. You’ll come away with a clear framework for understanding the physiology of speed, a practical approach to programming your speed practice, and — just as importantly — an understanding of why bad days happen and what to do about them.
Who This Is For
You might assume a lecture on speed is only for players chasing the fastest possible tempo. That’s one group who’ll benefit, but the content applies to every guitarist. As discussed in the lecture, there are at least three other reasons to engage with this material. First, time efficiency: if you know how to develop technique quickly and correctly, you can bank it and move on to the other things that matter to you. Second, the concept of headroom — being technically better than you need to be — means that even on difficult days, you can still play reliably. Third, if you teach, students who develop technique safely and efficiently stay happy, and happy students stick around.
Expression is the ultimate goal, but it’s done by the vehicle of technique.
The Physiology of Speed
Speed isn’t simply a matter of fast fingers. Muscular contraction starts in the brain, travels via the nervous system, and only then reaches the muscle. This means that nutrition, sleep, hydration, and psychological stress all directly affect your playing. A bad day on the guitar is often a biological event, not a musical one — understanding this shift in perspective is enormously empowering. The lecture introduces practical monitoring tools such as the ten-second dot test and a tremolo-picking test to help you gauge your central nervous system (CNS) fatigue before and during practice.
Equally important is the concept of minimum necessary tension. The common advice to “play without tension” is a myth. You need enough tension to produce the sound and stay in control — not more, not less. Learning to distinguish necessary tension from excess or unnecessary tension is a crucial skill.
The SAID Principle and Speed Bursts
The SAID principle — Specific Adaptation to Imposed Demands — means you get better at what you specifically train. To play fast, you must train fast. Practising slow makes you good at playing slowly; it doesn’t automatically transfer to higher tempos. The lecture distinguishes between Max Single Speed (MSS), the highest tempo you can play a passage once, and Max Cyclical Speed (MCS), the highest tempo you can sustain repeatedly. For advanced players especially, short speed bursts above the MSS are the key mechanism for pushing the ceiling upward.
Practice should be structured like athletic training: sets, reps, rest intervals, and intensity all matter. At higher tempos, use fewer repetitions and longer rest. At lower tempos, more reps with shorter rest are appropriate. The goal is minimum effective dose — enough stimulus to drive adaptation without causing overuse injury.
Mindset, Lifestyle, and Recovery
Guitar progress is inseparable from overall health. Sleep quality, nutrition, physical activity, and stress management all feed directly into your nervous system’s capacity to perform fine motor skills. Recognising the impact of life circumstances — a hard workout the day before, a poor night’s sleep, gig nerves — and being kind to yourself on low-performance days isn’t an excuse; it’s good science. The lecture also highlights micro-dosing practice — short, spaced-out sessions — as often more effective than long blocks, especially when CNS fatigue is a factor.
Taking it further
The lecture covers a cheat sheet for structuring speed practice into sets and reps. Download it and use it as a guide for your next technique session. Over time, keep a short log of how your playing feels each day alongside notes on sleep and stress — you’ll start to see patterns that let you practise smarter rather than just harder.
Your homework
Before your next three practice sessions, run a quick CNS check: do a brief tremolo-picking burst and note how it feels compared to your best. Then structure one technique exercise as a proper speed session — identify your current MCS for the passage, do three to five short bursts above that tempo, and rest fully between each one. Keep the total burst work under five minutes and notice how it affects your next session.
